So I'm working on a new load for my .308 AR. I am getting wildly different data on powder loads depending on what source I use. I will be using a Hornady 165 gain SST bullet. I plan to use Hodgdon Varget for the powder. From Hornady's reloading book I get 37.6 gr to 43.2gr. for available charge weights. From the Hodgdon website I get 42.0 to 46.0C. Not really sure which one to use at this point. Any insight would be great! Thanks!
